Both make the sound of the instrument loud enough for the performers and audience to hear. It even produces an electric signal when played. It can electronically manipulate the shape of the tone using an equalizer . It has a huge variety of electronic sound effects.
Principle of electromagnetic induction is utilized in electric guitars
There is a principle of direct Electromagnetic induction is applied. These signals are generated due to this only. It is nothing but a magnetic pickup. It is a commonly used principle. The vibration of playing guitar and the signal generated is too weak to drive a loudspeaker. Primarily it is plugged into a guitar amplifier before it is being sent to a loudspeaker. It produces vibration and makes a sound louder enough to hear. The generated output of an electric guitar is an electric signal.
This signal can easily be altered by electronic circuits to manipulate the sound or any modification or change of the sound required. Often the signal is modified using classified sound effects such as reverb , distortion and overdrive. The growling sound of the latter will act as a key element of the sound of the electric guitar.
